AC/DC DIN-Rail Power Supplies
Wide-range single-phase input, high efficiency and generous power reserve for 24 V, 48 V and custom control voltages in cabinets with limited rail space.
View seriesCAMTEC develops and manufactures switch mode power supplies (SMPS) and power assemblies for the automation sector, machine building and the electronics industry. Design, prototyping, SMD assembly, burn-in and final test all happen at our facility in Pfinztal near Karlsruhe – so the engineer who specifies a unit is the engineer who can change it.
The portfolio covers AC/DC power and DC/DC converters for DIN-rail, chassis mount, open frame and 19-inch rack mount installation, plus programmable DIN-rail supplies that replace bulky laboratory instruments in test automation cells.
From a 10 W sensor supply to a 100 kW programmable rectifier: every CAMTEC family shares the same protection philosophy, diagnostic signalling and mechanical logic, which keeps engineering and spare-part handling simple across a whole machine fleet.
Wide-range single-phase input, high efficiency and generous power reserve for 24 V, 48 V and custom control voltages in cabinets with limited rail space.
View seriesBalanced load on all phases, low ripple and stable hold-up for drive cabinets, conveyor lines and heavy-duty handling systems.
View seriesSet-point control of voltage and current for end-of-line test, burn-in and laboratory-style automation – DIN-rail or cabinet mounted instead of a bench instrument.
View seriesEmbedded, parallelable power stages for high-current DC systems; scale output by adding modules instead of redesigning the cabinet.
View seriesUnbreakable DC architecture: buffer modules, temperature-compensated chargers and redundancy modules that keep PLCs alive through mains dips.
View seriesStep-down converters for DC mini-grid and micro-grid topologies where PV, storage and drives share one high-voltage DC backbone.
View seriesStandard 3U subrack solutions for control rooms, test racks and telecom-style infrastructure with front-accessible status indication.
View seriesControlled ramp-up of capacitive and transformer loads so upstream breakers and contactors stop nuisance-tripping at switch-on.
View seriesSemiconductor switching for DC loads: no arcing, no contact erosion, millions of cycles – ideal where mechanical relays become a maintenance item.

| Application scenario | Recommended platform | Typical power | Key benefit |
|---|---|---|---|
| Standard machine control cabinet, 1-phase mains | AC/DC DIN-Rail 1PH | 10 W – 2000 W | Compact footprint, wide input range |
| Drive-heavy line with 400 V three-phase supply | AC/DC DIN-Rail 3PH | 480 W – 1000 W | Balanced phase load, low ripple |
| End-of-line test bench / burn-in chamber | Programmable DC Supply | 480 W – 100 kW | Remote set-point for U and I |
| High-current DC bus, expandable later | Rack-/Wall-Mount Embedded | 2 kW – 100 kW | Modular parallel scaling |
| Controlled shut-down on mains failure | DC-UPS & Charging Rectifier | 480 W – 105 kW | Battery buffering and charge management |
| PV / storage DC backbone, 450–820 V DC | DC/DC Mini-Grid Converter | DIN-rail range | Direct DC-to-DC without inverter stage |
| Breaker trips when large loads switch on | ESB Inrush Current Limiter | 3.6 kW – 46 kW | Soft charge of capacitive loads |
| Frequent DC switching, no maintenance allowed | UMS DC MosFET Relay | Wide load range | Arc-free, wearless operation |
Purchasing a power supply is a ten-year decision: it determines machine uptime, service cost and certification effort. These four points are what our OEM customers cite most often.
ISO 9001:2015 processes, TÜV-inspected FAB, UL and CSA compliant designs, 100 % electrical final test and documented burn-in for professional series.
High efficiency across the load curve, real power reserve, wide temperature operation and EMC margins that survive harsh industrial mains.
Modified voltages, connector sets, coatings, labelling and firmware parameters – engineered and released by the same team that builds the standard range.
A distributor and sales-partner network supports specification, local stock and after-sales service in Europe, North America and Asia.
A CAMTEC switch mode power supply is dimensioned for pro-applications: infrastructure, railway systems, traffic control, energy and military-grade installations. These sectors share long service intervals, wide temperature windows and unforgiving mains conditions – exactly the conditions our derating and protection concepts are built around.
Everything an OEM audit or import file usually requires is published openly – no registration needed.
